| MTBF| 5708.9K hrs min. Telcordia SR-332 (Bellcore); 700.1K hrs min.| MIL-HDBK-217F (25℃)
DIMENSION| 1183526mm (LWH)
PACKING| 0.22Kg; 60pcs/14.2Kg/0.72CUFT
NOTE| 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load, and 25℃ of ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3. Tolerance: includes set up tolerance, line regulation, and load regulation.

4. Derating may be needed under low input voltage. Please check the static characteristics for more details.

5. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify the EMC Directive on the complete installation.

(as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)

6. Length of set up time is measured at the first cold start. Turning ON/OFF the power supply may lead to an increase in the set-up time.

7. Suitable for indoor use or outdoor use without direct sunlight exposure. Please avoid immersing in the water for over 30 minutes.

8. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitudes higher than 2000m(6500ft).

9. For any application note and IP waterproof function installation caution, please refer to our user manual before using. https:// www.meanwell.com/Upload/PDF/LED EN.pdf

10. This product is not intended for LED lighting luminaire applications in the EU. (In the EU the LPF/NPF/XLG series are recommended.)
